About snapping up the Internet, do you really know

Limited, which originated in France site Vente Priv e e to retail trading activities through the medium of the Internet, for a limited period of time, providing small quantity, huge discounts and benefits of commodity buying. This Web site introduced by other countries to follow suit soon, and China is no exception,, Jingdong, suning shopping site Taobao almost on a daily basis to carry out various forms of buying activities, train tickets snapped up every year, many of them are new products on sale to snap up the most vast and Grand nature is double 11. After a shopping spree in earlier years, various techniques have greatly improved, especially in China's greater population density, net name, populous country, snapping up technology requires even more.

Before buying event, the seller would have done a lot of publicity, that led many people to purchase interface, pay attention to this activity. Started snapping up, large numbers of people into purchasing interface, if the server crashes, what is the situation?

Buying problems

1, server pressure

Carnival, billions of people behind the great instantaneous trading is extremely powerful technological support, tens of thousands of servers, millions of lines of code, and numerous advanced technologies. 1 systems support to 10,000, 100,000 and million users is not an order of magnitude, simply by adding more servers has been unable to solve these problems.

For General Web site, snapping up does not occur every day, even if it is Taobao, Jingdong, nor double 11, and 12 every day so many people rush to buy goods, often snapping up activity sent in a few items, some small moments, before the double 11 activities, Taobao's technical team for the elaborate layout and planning of activities, all kinds of pressure and extreme tests and so on. Ahead of the launch will also gain a lot of network bandwidth and servers, and so on, but the buying activity may not last if it goes into a lot of hardware resources is not cost-effective.

2, technical pressures

Snapping up technology demand is still very high, many companies have begun to do e-commerce, occasionally snapping up under, however bad, so each snapped up collapsed. When Taobao had just snapped up most often collapse, they have gone through many craters have today's achievements.

3, cattle

Rush will certainly attract a lot of people interested in this product and people interested in making money, in short supply will inevitably lead to cattle, all large numbers of cattle into the rush of flood, the result is truly interested in people not buy goods, scalpers earned big bucks. For businesses, both good and bad, I sell the popularity I also earn, cattle fare sale merchandise, provided the value of my product

Network snapped up mode Xia of cattle are is technology party, has no longer is tinkering around the, some team specifically recruitment technicians, for specific of website wrote script, participation to each of snapped up activities, user of page refresh, and click, in technology party of hands became very simple, several line code on can Executive snapped up operation, script Executive of speed is far from manual click can than of, you on brain fill Xia skateboard shoes and car of speed gap good has.

4, the consequences of failure

We have the passion involved in buying again and again, every time Rob can't do that, but still hold a try to attempt this way. If you really want to, people who love this product, snapping up failed inevitably sad, some people will lose confidence in the seller. Author is also snapping up its battle-scarred, snapped up experienced many times when the system crashes, and die all the time, feeling great sorrow or great joy, but that's really okay?

If the server crashes snapping up failed? Website just when it started to do this kind of activity is likely to go down, snapping up the server is a cluster, if one is no problem, hardware can make up for it. Overall downtime often can't restart time, very serious consequences, sellers customer service phone been ringing, and network above all criticism, followed by negative and so on, so that buying has been a double-edged sword, fix cut himself with a knife.

Next generation buying programme

The rapid development of the Internet, new technologies have been developed from generation to generation, snapping up this pattern will continue, interest will drive the technology and model innovation.

1, make an appointment to buy

Case study: Hammer phone appointments, millet's appointment to snap up

Appointment is just a purchase eligibility is not something you can buy, for a long period of time for the user to confirm product, such appointments are free either to deposit, make an appointment there at all, no matter how's activities, in cases was not enough to force the server, purchased with a reservation is indeed a very good form. Appointment can see user on products of interest, market of response, can is good of estimates snapped up day of server pressure, cost control has, does not caused production waste or merchandise backlog, accounted for paragraph reduced has, due to presale needs buyers first payment, manufacturers just do supply chain on good, without advance himself has funds, to purchased fixed of form, on sellers for hundred Lee and no a harm.

2, code purchase

Case in point: code f millet and Le le code, Meizu m-codes

Business open to the right of first refusal, when purchased in the goods has not been opened, emit less code to some really liked the product or VIP users. Open a back door

3, lottery purchase

Case study: group 0 to snap up

Anyone else should have the same right to buy, equal opportunities, why items have to go to scalpers there? Each individual gets snapped up users into a single code, buying after the early trading based on current stock data, according to some mathematical calculations and transformations to figure out a winning number, everyone can use the same method to calculate winning numbers, so that everyone has equal rights to buy, fair or reflected.

4, mobile buying

Case study: app rush

When active only ends when buying, snapping up front for the better, when he started writing good scripts cannot run so easily, some activities in the app page, micro-letter of authorization must be made before it can be. Common developer is hard to simulate a micro-browser environment. Scalpers buying activity is easy to operate the computer, but only if businesses opening up mobile buying spree, scalping will not be so easy.

5, better technology and architecture

Case in point: Ali, East of cloud-computing services

As the most populous country, snapping up challenge is also the largest in China, Taobao had just started when the server is often down, was also snapped the crashes, till today, technically a relatively stable, their minds are also spread throughout the home, no one can take off, experienced Taobao has changed. They accumulated many years of experience in technology and meet the challenges again and again, have established their own cloud computing and are willing to open their technology and achieve win-win. I hate to reinvent the wheel, writing code, new technologies will be applied to many areas, not necessarily every company to open a buy programme and technical, standing on the shoulders of Giants to go faster, stronger.
